Abstract
The utility model relates to a skeleton enclose inflatable seal device belongs to the solid -liquid separation technology field. Technical scheme is: a skeleton enclose inflatable seal device mainly constitutes characterized in that by skeleton body, filler ring, opening sealing washer, air cock, double -screw bolt, nut, sealing washer (1), sealing washer (2): skeleton body is equipped with the ring packing groove, and the excircle is equipped with the boss, the opening portion of opening sealing washer by the filler ring through impress together skeleton body's annular close inslot of double -screw bolt, skeleton body surrounds whole opening sealing washer completely, the hanger bolt adds the mounting means that the briquetting compressed tightly the boss, fixes skeleton body on the body of storehouse, the last plane of skeleton body hookup hole both sides are equipped with the sealed recess of twice for installation sealing washer (1) and sealing washer (2) mainly make the storehouse body and opening sealing washer internal pressure gas not from cooperating the plane leakage.
Description
Technical field
This utility model relates to a kind of skeleton enclosed air inflation sealing device, it is adaptable to the sealing of pressing filter blow-off valve, belongs to solid-liquid separation technique field.
Background technology
A kind of Patent No. 96245055.3 utility model patent " a kind of Assembled aerated sealer " is for the sealing of pressing filter blow-off valve, good sealing effect, but processing and fabricating, transport and assemble in have the disadvantage that 1, Assembled aerated sealer is entirely enclosed in the lower end annular seal groove in the Shang Cang of blow-off valve, lower storehouse, lower end annular seal groove requirement on machining accuracy is high, and Shang Cang, Xia Cang of blow-off valve are 2.5 meters high, the cylinder that diameter is 1.4 meters, the difficulty of processing of annular seal groove is big；2, after Assembled aerated sealer assembles, pressure ring and filler ring are at the opening part of opening sealing ring to folder, and opening sealing ring material is rubber, and after assembling, major part is exposed, needs protection, sometimes because transporting improper damage opening sealing ring in transport；3, when scene replaces with the Assembled aerated sealer in storehouse, 2 bit manipulation personnel must stand in a diameter of 1.4 meters, it is highly in the lower storehouse of 2.5 meters, in being held in the palm the lower end annular seal groove loading upper storehouse, due to restriction and the responsibility problem of maintainer of working place, easily there is the situation that assembling is not in place, cause sealing ring not completely in annular seal groove, flashboard is plane and opening sealing ring phase mutual friction on it in running, reduces the service life of gas-flow closure circle.
This utility model is the deficiency in order to overcome former Assembled aerated sealer to exist, it is provided that a kind of skeleton enclosed air inflation sealing device.
Summary of the invention
This utility model be the technical scheme is that a kind of skeleton enclosed air inflation sealing device, mainly it is made up of skeleton body, filler ring, opening sealing ring, valve, stud, nut, sealing ring (1), sealing ring (2), it is characterized by: skeleton body is provided with annular seal groove, cylindrical is provided with boss, Shang Cang, the lower end in lower storehouse only process the seam coordinated with boss crest clearance, and processing is simple；Skeleton enclosed air inflation sealing device can be realized assembling by 1 bit manipulation personnel outside storehouse, during assembling, the opening portion of opening sealing ring is pressed in the close groove of annular of skeleton body by stud together by filler ring, the sealing realizing opening part can be compressed in the opening portion of opening sealing ring by back tightening nut, assembling back skeleton body surrounds whole opening sealing ring completely, and transport split shed sealing ring is hardly damaged；During on-the-spot replacing skeleton enclosed air inflation sealing device, by 2 bit manipulation personnel, skeleton enclosed air inflation sealing device is aligned warehouse seam to position, the mounting means of boss is compressed by hanger bolt pressurizing block, skeleton body is fixed on warehouse, easy for installation, quick, the high life of opening sealing ring；On skeleton body, plane connection holes both sides are provided with two seals groove, are used for installing sealing ring (1) and sealing ring (2), and in mainly making warehouse and opening sealing ring, pressed gas is from coordinating leakage at plane, it is ensured that the pressure stability in warehouse and opening sealing ring.
` the beneficial effects of the utility model are: the processing of whole device is simple, easy for installation, quick, length in service life, maintenance cost are low, workman labor intensity is low.
